Change in state

1
Change in state conversion from one physical
form to another
2
Temperature measures speed of the particles
movement

• More thermal energy Temp increases particles
  move faster change in state

3
Melting from solid to liquid
4
Melting point temp at which a solid melts
Ex. Water 0 C or 32 F
5
Freezing from liquid to solid
6
Freezing point temp. at which a liquid freezes

• Ex. Water 0 C 32 F

7
Vaporization change from liquid to a gas

• 1. Boiling - occurs throughout the liquid

1. Evaporation occurs at the surface of the liquid
